    • Predicting Foraging Habitat of European Shags - A Multi-Year and Multi-Colony Tracking Approach to Identify Important Areas for Marine Conservation 

      Dehnhard, Nina; Mattisson, Jenny; Tarroux, Arnaud; Anker-Nilssen, Tycho; Lorentsen, Svein-Håkon; Christensen-Dalsgaard, Signe (Peer reviewed; Journal article, 2022)
      Human activity in the coastal zone is increasing worldwide, putting a number of seabird species under pressure. Norway is no exception to this development, and with > 35% of the NE Atlantic population of the currently ...

    • Prey predictability and preparation versus recovery breathing strategies in European shags Gulosus aristotelis (L.) diving in different habitats 

      Carlsen, Astrid A.; Wright, Jonathan; Lorentsen, Svein-Håkon; Lea, Stephen E.G. (Peer reviewed; Journal article, 2023)
      A recent study on the diving behaviour of European shags (Gulosus aristotelis (L.)) foraging in kelp forests off rocky coasts of Norway suggests surface durations are related only to the duration of the preceding dive, and ...

    • Reproductive success in the European shag is linked to annual variation in diet and foraging trip metrics 

      Lorentsen, Svein-Håkon; Mattisson, Jenny; Christensen-Dalsgaard, Signe (Journal article, 2019)
      Seabird populations have declined worldwide, and several of the potential threats are of anthropogenic origin. To understand how changes in seabird populations relate to environmental conditions it is important to know the ...

    • Temporal non-independence of foraging dive and surface duration sequences in the European shag Gulosus aristotelis 

      Carlsen, Astrid A.; Lorentsen, Svein-Håkon; Mattisson, Jenny; Wright, J. (Peer reviewed; Journal article, 2023)
      Studies of foraging behaviour and respiratory physiology in breath-holding divers often assume that each dive cycle (dive plus surface duration) is physiologically and ecologically independent within a series (or “bout”) ...
